SPECIFICATION forming part of Letters Patent N o. 442,041, datedDecember 2, 1890.

Application led August 5 1890.

To aZZ whom, it may concern,.-

Be it known that I, HENRY C. HART, of Detroit, in the county of NVayneand State of Michigan, have invented a new and useful Improvement inTater-Closets, of which the following is a specification.

My invention consists in an improvement in water-closets, hereinafterfully described and claimed.

Figure l is a side elevation, partly in section. Fig. 2 is a plan viewomitting the tank. Fig. 3 is a rear elevation. Figs. 4 and 5 are sideand rear views of the locking-pawl and its connections. Figs. 6 and 7are enlarged side and rear elevations of a portion of the mechanism.

This apparatus is similar to that shown and described in my applicationfor patent filed May` 12, 1890, Serial No. 351,503, the main differencebeing that in this apparatus the measuring-pipe serves as a balance forthe pan, holding the pan raised when said pipe is full of water, andvice versa.

A represents an elevated tank having' an outlet-pipe c, the lower end ofwhich is connected with a three-way cock F.

C represents the lid of the closet, connected rigidly by hinges w w witha spindle fw', one end of which turns in a bearing I on the closet, andthe other end of which (marked p) is connected with the plug o of cockF.

D represents the bowl, E the hopper, n the casing, and m the seat, of apan-closet.

M represents a swinging service-pan carried on shaft M', journaled inthe hopper.

Zrepresents a lever secured on shaft M', having one or more teeth formedon its end.

B represents a measuring-pi pe rising above the level of the water intank A. As shown, a smaller pipe b rises through a passage b in tank A,which passage guides and steadies said pipe B.

Q represents a flexible pipe or hose which connects pipe B with cock F,and the outlet g of cock F is connected with the interior of `bowl D atZt by pipe g. Z3 represents a guide for the lower part of pipe B.

B represents a rod secured to the lower end of pipe B and continuingdownward, passing through the end of a spring 7c, which serves both as aguide and a stop.

K represents an arm secured on rod B', and

Serial No. 361,039. (No model.)

the end of said arm is connected by a link Z' with lever Z, both ends ofsaid link being pivotally connected, so that the whole weight of pipe Bis carried by lever Z, thus balancing pipe B and pan M on shaft M.

e represents an arm secured on lid C, carrying at its end a pivoted dogf, which swings freely in one direction, but is prevented from swingingin the other direction by its upper endf coming in Contact with the ende of arm e.

I represents a pawl adapted to engage with the teeth on lever Z, andheld in proper position therefor by a counter-weight t'. This pawl issecured on a shaft journaled in the hopper.

I represents a lever secured on the shaft which carries pawl I', and hasa curved end, adapting it to be operated by dog f, and when said leveris forced downward by said dog pawl I is withdrawn from engagement withlever Z.

.I represents a rod by which pawl I can be pushed back and held ont ofengagement with lever Z when the water in tank A is exhausted.

The operation of my invent-ion is as follows: lVhen lid C is closed, thethree-way cock F is in such position that water from tank A fiowsthrough pipe c, cock F, and hose Q., into pipe B, thus filling said pipewith water to the level ot' the water in tank A. In this condition pipeB, with its contents resting upon leverZ by means of arm K and link Zoverbalances pan M and holds it raised, as shown in full lines in Fig.6. In this position pawl I locks lever Z, as shown in Fig. l. Then lid Cis raised, the plug of cock F is rotated so as to close the connectionbetween pipes c B and open the connection from pipe B to the outlet g ofsaid cock, thus discharging the water in pipe B into the pan M. The panand its contents are now heavier than pipe B, and said parts wouldassume the position shown in dotted lines in Fig. 6, but for pawl Iwhich locks lever Z. Then lid C is again closed, the dog f rides downlever I", thus temporarily withdrawing pawl I from lever Z andpermitting the pan to dump. The connection between pipe B and the outletg' of cock F is closed, and that between pipes c B is opened by closinglid C, so that IOC pipe B overbalances ,panv M and raises said pan toits normal position, in which Ait is locked by pawl I. When there is nowater in tank A, the pawl l may be pushed back by rod J, thus allowingpan M to remain down and converting the closet into a hopper-closet.

Vhat I claim as my invention, and desire to secure by Letters Patent,is.

1. The combination, with a Water-closet bowl, a swinging service pautherefor, and a tank, of a movable Ineasuring-vessel receiving waterfrom the tank, and connections acted on by the measuring-vessel whensupplied with Water to balance theweight of the Service-pan,substantially as described.
